Vehicle Miles Traveled

Vehicle Miles Traveled (VMT) is a unit that measures travel distance made by a vehicle, such as an automobile, van, pickup truck, commercial vehicle, or motorcycle. This measure reflects total year 2040 forecasted islandwide VMT produced by the CMP project package for all facility and area types for the two-hour AM peak period. Projects in a CMP package that show a decrease in VMT receive two points, one point for no change, and zero points for an increase in VMT.

The table below shows the island-wide change in VMT by facility type and area type. For scoring, the change in total VMT is used. Because no single project can have a dramatic influence on island-wide VMT, changes of any amount are scored as an increase or decrease.

Vehicle Hours Traveled

Vehicle Hours Traveled (VHT) is a measurement of the total hours traveled by all vehicles. It is calculated by multiplying the number of vehicles times the travel time of those vehicles on a network or specific links within that network. VHT is an indicator of how additional travel demand influences congestion in the system from a travel time standpoint. This measure reflects total year 2040 forecasted islandwide VHT produced by the CMP project package for all facility and area types for the two-hour AM peak period. Projects in a CMP package that show a decrease in VHT receive two points, one point for no change, and zero points for an increase in VHT.

The table below shows the island-wide change in VHT by facility type and area type. For scoring, the change in total VHT is used. Because no single project can have a dramatic influence on island-wide VHT, changes of any amount are scored as an increase or decrease.

Delay

Vehicle Hours of Delay (VHD) is defined as the difference between vehicle-hours traveled under congested conditions and vehicle hours of travel that would otherwise be expected under free flow (uncongested) conditions. VHD is calculated using travel times and travel speeds. This measure reflects total year 2040 forecasted islandwide VHD produced by the CMP project package for all facility and area types for the two-hour AM peak period. Projects in a CMP package that show a decrease in VHD receive two points, one point for no change, and zero points for an increase in VHD.

The table below shows the island-wide change in VHD by facility type and area type. For scoring, the change in total VHD is used. Because no single project can have a dramatic influence on island-wide VHD, changes of any amount are scored as an increase or decrease.

Spot Metrics

For spot measurements, a representative link or links is selected. The representative links are highlighted red in the project map. Each metric shows the before and after value, and whether it is considered an increase or a decrease.

Spot Volume Change

Vehicle volume is the number of vehicles that use a given roadway over a specified period of time. Vehicle volumes are presented in concert with V/C ratio to provide a comparison of project effectiveness. For example, does the project (or projects) in a CMP project package reduce congestion (reduced V/C ratio), while carrying more traffic (higher vehicle volumes)? For this particular metric, points are assigned based on the ability of project to show higher vehicle volumes on an existing facility. Points range from zero for no change in comparison to the Baseline alternative during the AM peak period up to eight points for increases in vehicle volumes between 3,501 to 4,000 vehicle trips.

The table below shows the change in volume during the AM period. Changes less than 10% are considered no change for scoring.
